0.4 Plasma Torch Parts Wear & Replacement
It is very important to recognise that plasma torch consumables wear as part of normal operaon and
should be replaced in a mely manner.
Operang a torch with worn consumables will cause poor cung results and possible damage to the torch
and machine itself. Damage caused by unmely replacement of consumables will not be covered by
warranty.
Use the following guidelines to determine when consumables should be replaced:
Cung Tips: The cung p has
a small calibrated orifice that the plasma passes through. If the orifice
becomes parally blocked, deformed or enlarged, the cung p should be replaced.
Electrodes: The electrode has a small silver ‘hafnium’ insert in the end of the p. This is what generates the
plasma ions. Once the hafnium insert is gone or is damaged the p must be replaced.
Swirl Ring: This should be replaced if broken, chipped, cracked, worn or badly heat damaged. The small air
holes do wear ov
er me. Whilst it is not usually visible with naked eye it can cause the flow & swirl of the
air to be disrupted with causes an unstable or deformed arc.
Retaining Cap: This should be replaced if broken, chipped, cracked or badly heat damaged.
Tips and electrodes: These should wear reasonably evenly and it is normal pracce to replace them both
together. If a new p is inserted with a worn electrode the p will wear much more quickly than if the
electrod
e was also replaced at that same me. If ps or electrodes are wearing much faster than the other
component it is likely to be caused by one of the following:
Wet or dirty air supply
Incorrect air supply
Poor operator technique
Damaged torch head

It is also very important to only use genuine Strata consumables and parts for the plasma torch. They
are engineered to suit the machine and non-genuine items may cause lack of performance, short life span,
torch and machine damage and
void warranty.
